I figured as much. I wish I had gone with the 4 GB version instead. On that topic, would it be possible, and sensible, to sli my 2 GB with a 4 GB?
And with just the 2x 2GB 670's, if I'm not looking for super ultra max settings, and more like medium-ish, think it'd be possible to pull off 50-60+ frames in games such as BF3, Skyrim, Far Car 3?
